摘要： 研究了二甲四氯不同用量对单子叶禾本科草坪草生长发育的影响和对草坪杂草的杀伤效果，结果表明：用量在6000g/hm2以上时，对草坪草就会产生轻度药害，且用量愈大，药害愈重；用量低于1500g/hm2，效果不明显。提出了二甲四氯每次经济有效的用量为3000~4500g/hm2，每年施用2~4次，基本可以控制杂草。指出了二甲四氯应用条件和注意事项(如：最大用量不宜超过12000g/hm2)，为防除草坪杂草提供了科学依据。

Abstract: This paper deals with the full study and analysis on the effects of MCPA on monocotyledonous turf and the control effectiveness to the lawn weeds in different dosages. The experiment results shown that: When the dosage is larger than 6000g/hm2, slight phytotoxic effect occurred. The larger dosage, the server the phytotoxic effect. When the dosage is less than 1500g/hm2, weed control effects were not evident. The economically rational dosage of MCPA is set as 3000~4500g /hm2. The lawn weeds can be effectively control at 2~4 applications annually. The application conditions and precautions of MCPA were also proposed which serves as scientific foundations for lawn weeds control.
